TPA6138A2PWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | +INR | input | Right-channel positive input; input voltage range VSS - 0.3 V to VDD + 0.3 V. |
| 2 | -INR | input | Right-channel negative input; input voltage range VSS - 0.3 V to VDD + 0.3 V. |
| 3 | OUTR | output | Right-channel output; provides 40 mW at 1% THD+N into 32 Ω with 3.3 V supply, output range ±3.05 V, minimum load 12.8 Ω. |
| 4 | GND | power_in | Ground reference. |
| 5 | Mute | input | Mute control, active-low; low level (0 to 40% VDD) mutes output, high level (60% VDD and above) enables output. |
| 6 | VSS | power_in | Supply voltage return; internal charge pump generates negative rail connected to this pin. |
| 7 | CN | bidirectional | Charge-pump flying capacitor negative connection; external capacitor value typically 1 µF for optimal performance. |
| 8 | CP | bidirectional | Charge-pump flying capacitor positive connection; external capacitor value typically 1 µF for optimal performance. |
| 9 | VDD | power_in | Positive supply voltage input; recommended operating range 3.0 V to 3.6 V. |
| 10 | GND | power_in | Ground reference. |
| 11 | UVP | input | Undervoltage protection input with internal pull-up; mutes output when voltage drops below threshold (typically 1.25 V via external resistor divider), unconnected if function unused. |
| 12 | OUTL | output | Left-channel output; provides 40 mW at 1% THD+N into 32 Ω with 3.3 V supply, output range ±3.05 V, minimum load 12.8 Ω. |
| 13 | -INL | input | Left-channel negative input; input voltage range VSS - 0.3 V to VDD + 0.3 V. |
| 14 | +INL | input | Left-channel positive input; input voltage range VSS - 0.3 V to VDD + 0.3 V. |
